Last week I flew to Benghazi to meet Libya's Transitional National Council (TNC), a visit coordinated with European Union High Representative Catherine Ashton and NATO allies. What I saw reminded me of my country 20 years ago, just after Poland's first free elections.

Peoples in transition from authoritarian rule — peaceful in Poland in 1989, bloody in Libya today—grapple with decisions that determine their fate for decades.

How should the former regime's worst wrongdoers and security police, with their insidious archives, be treated? Should the former ruling party be banned? How can civilian, democratic control of the army and police be secured? What role should religion play in public affairs? Should the constitution establish a presidential or parliamentary system?
